Kind of related to rules, commands, and
tools. There also is a special file you can add
projects. Here, I'm back in a Python project,
project. It's a .cursorignore
file, and it acts like a git ignore file.
It allows you to specify files cursor should never be
allowed to look at. For example, my .env file which contains
environment variables I don't want to expose, not to cursor, not to anyone
else. Now, in case of .env, you actually don't need to
add them here because .env is a special file that is ignored by
default anyways, which you can tell by this icon.
Nonetheless, as an example, we can add it here again.
And you could add any other files you don't want cursor to inspect
like the .venv file which contains the virtual environment,
So if you have any code, any files that should not be considered by cursor,
adding them to such a .cursorignore file is a good idea.
